In this study, a Hamilton motion has been defined in four-dimensional Euclidean space E4, and it is shown that this is a homothetic motion. Furthermore, it has been found that the Hamilton motion defined by a regular curve of order r has only one acceleration centre of order (r - 1) at every t-instant.
